JV’s Power Tips for PHP (2) - Conclusion

(Page 7 of 7 )

This article has not been so much about showing you one way to do things, as it has been about adding new colours and concepts to your programming palette. Who knows? There may be a time in the future when you are presented with a problem and you think back to some of the concepts I described and realize they might just make your life a little bit easier…

The main concepts in bullet point:

1. You can evaluate a single variable in an if statement (inc. arrays/objects)
2. Abstract form input to protect against SQL injection
3. Use {} so you don’t have to break “‘s when printing assigning variables.
4. How to use array elements to decide what to display instead of if statements
5. How to use & to shortcut to $_POST and make naming easier
6. Create indexed arrays on the fly with []
7. Create arbitrary arrays on the fly with [‘any’][‘text’]
8. Using ?:; to determine dynamic content output
9. Wrapping up ?:; in () like so (?:) for use within assignment or echo
10. Using an array to store key values for use in conditional iteration
11. Using foreach for easy iteration and value access
12. Try not to use redundant code (i.e. don’t write the same thing twice)

Once again I haven’t covered as much ground as I would have liked. I guess that will just have to wait for the next instalment(s) of <announcers voice>JV’s Power Tips For PHP</announcers voice>. I also have a website that offers, amongst other things, free scripts that can help to make a PHP programmer’s job easier too.

Anyway, thanks for your time.
